Hi, everyone

 

ADV7842 Hardware reference manual(HRM) explains that the unused pin left open circuit. does not connect any parts,

This "TRI1, Miscellaneous analog, Float this pin" is description of HRM at 536 page.

 

But on the evaluation board TRI1,2,3,4 pins are terminated by pull-down register of 0 ohm.

 

Which is better circuit for TRI1,2,34 pins?
Could you please let me know what is better?

 

thank you
